preferably potassium carbonate" (col. 8, lines 5-7).
12. X of Bisacchi Compound 13 is a "leaving group"
(col. 3, line 64) such as trifluoromethanesulfonyloxy (triflyl;
CF )SO)O) ) (col. 3, lines 66-67), corresponding to applicants'
3
claimed X which can be, inter alia, a perfluoroalkane sulfonyloxy
group. The Bisacchi X can also be methanesulfonyloxy (mesyl;
